IKE (Internet Key Exchange) is a fundamental component of IPsec, responsible for authenticating peers and securely exchanging cryptographic keys used for data encryption and integrity.
Common mistakes.
- B. Data encryption itself is performed by IPsec's Encapsulating Security Payload (ESP) protocol, not IKE.
- C. Data signature for integrity is handled by IPsec's Authentication Header (AH) or ESP with authentication, while IKE is for key management.
- D. Enforcing quality of service (QoS) is outside the scope of IKE's primary function in IPsec.
